BENCHMARKING AWS LAMBDA COLD STARTS ACROSS JAVASCRIPT RUNTIMES

Summary from the TLDR Web Dev newsletter

This article benchmarks the cold start performance of AWS Lambda functions using Deno, Node.js, and Python runtimes. Deno shows significantly better performance with faster startup times, especially in smaller function configurations. This is likely due to Deno's various runtime caches. You can make your Deno app start time even faster by populating these caches ahead of time during the Docker image creation so that they're immediately available when your application executes in AWS Lambda.
